To a]! whom, it may concern: l

Be it known that we, W ILLIAM MATHER, l J ULIUS Hessian, and WxLLiAM JACKSON l Porn, subjects of His Majesty the of Great Britain, and residents of Manchester, England, have invented a new and useful Improved Apparatus for Mercerizing, of which the following is a specification.

The invention relates to ap aratus for mer cerizing fabrics and materia s-such as fine muslins, lace, yarns, and the like, as well as unspun cotton-with the object of providing an apparatus in which the diiiicult-y hitherto met with of treatingmateriais of loose and delicate structure is overcome by providing means whereby it is prevented from contracting while under the influence of the mercerizing iiquidwith which it is treated while passing in a continuous manner through the apparatus.

In the accompanying drawings, Figure 1 is a longitudinal section through so much of an apparatus of our improved construction as is necessary to illustrate its working. Fig. 2 is a transverse section therethrough. Fig. 3 is a transverse section of a detailed part of Fig. l, drawn to a larger scale. Figs. 4 and 5 are respectively a broken plan and elevation of the part shown in Fi 3. Figs. 6, 7, and 8 are sectional views 0' detailed modifications of part of the apparatus, and Fig 9 is a die. grammatic view of a modified form of apparatus.

The up aratus illustrated in Figs. 1 and 2 is part-icu arly applicable to the mercerization of loose or unspun cotton and consists of an upper pervious band or a ron l and a lower ertorated flexible be 2, between which t is sheets 3 of material are compressed during their passage through the machine, so as to prevent orininimize the contraction of the fibers.

T he upper pervious band 1 may be a web of wire-gauze or may consist of a number of parallel Wires, rods, lathe, or the like, oi any suitable material, attached at its edges to flexible linked chains 4, traveling on rails 5, carried by supports 6 on either side of the apparatus, said chains passing over pulleys 7, mounted in bearings 8, carried in frames 9 at either end of the apparatus to iorman endless traveling band, said pulleys being driven in any suitable manner from any convenient source of power.

The lower perforated flexible bed may be constituted by narrow perforated sectional plates 2 of metal or other suitable material, extending across the apparatus. The plates may be curved, as shown in Fig. 2, and the upper surfaces may be either flat or provided with ridges or grooves. The plates are connected by links 11 and travel on side rails 12, as in the case of the upper band I, similarly supported M13, and over pulleys 10, also similarl Y carried on the frame 9.

he rails 5 and 12, Where they meet, may be combined, as shown, in the form of a channel-section.

The material to be mercerizcd is passed in over guide-rollers 14 in the direction of the arrow and is immediately subjected to the action of a steaming device 15 and a saturatiIi-g device 16, whereby steam and Water or a weak solution of caustic from any convenient sources of supply are caused to percolate through the material while held between the band 1- and bed .2.

Squeezing-rollers 18 are provided adjustable in bearings 19 as to their pressure by a screw 20 and compression-s ring 21, whereby the moisture is squeezed from the material preparatory to its being subjected to the strong caustic liquid or mercerizing agent, which is then caused to percolate through the material from a supply device 23 in connection with a convenient source of supply.

The means whereby ressure of the upper pervious traveling band 1 upon the material contained between it and the lower traveling bed 2 is obtained is shown in detail in part in Figs. 3, 4-, and 5, comprises widening-pieces 24, arranged on either side of the machine, the under faces 24* of which curved to correspond with the curved surface of the platesQ, forming the lower bed and between which and the under faces 24 of said wide'n ing-pieces the gauze or other flexible sheet forming the upper band 1 passes and is j owed to the links 4, which form the side chains guided on the combined u per and lower rails 12 and 5 and against which chains said widening pieces are adapted to abut, the tens1on= undergoing tl'ie mercerirring treatment. mnl: 25, divided into sections by trams- "alle 28,, is arranged, beneath the lower an mto nie" aft-:1 passing through and the bed 2 and from 1 either conveyecl beck tn v poetlve sources 0; supply-by means nipes 2?, m the divided tnnk 25 as term the snuree .of supply, the vnrs; being dr wn by any suitable fine deliveryifpes 27 and supeil' respective devices,
